Detectors- VDI offers DC biased detectors (DD) and zero biased detectors (ZBD). These detectors offer full waveguide band operation, high sensitivity, and high responsivity. Planar construction yields a mechanically robust design. These detectors are compact and simple to use. Follow this link to view a recent technical paper detailing how VDI measures detector noise and responsivity; Responsivity and Noise Measurements of Zero-Bias Schottky Diode Detectors.
